SARMIENTO-NAFATE, Saúl; GIL-LOPEZ, Heldail A  and  ARROYO, Daisy. Shrimp by-catch reduction using a short funnel net, in the Gulf of Tehuantepec, South Pacific, Mexico. Rev. biol. trop [online]. 2007, vol.55, n.3-4, pp.889-897. ISSN 0034-7744.

Reduction of the by-catch in shrimp fishery is an important goal worldwide. In order to compare by-catch using the conventional trawling net and a newly designed short funnel net, nine cruises were carried out by the commercial fleet operating in the Gulf of Tehuantepec, Mexico. A total of 480 trawls were done (mean duration: 85 min). The experimental trawls using the modified net produced a 21.13-28.86 % by-catch reduction (confidence interval 95 %), a 3 % increase of shrimp catch, and a significant reduction on net recovery time. Rev. Biol. Trop. 55 (3-4): 889-897. Epub 2007 December, 28.

Keywords : Shrimp trawling; by-catch; new net design.
